Variable Flow Control Valves maintain the flow rate of hydraulic fluid to a selected value. Applications include hydraulic cylinders requiring constant extension or retraction speeds and hydraulic motors requiring constant rotational speeds. When used with a fixed delivery pump the excess flow is By-Passed across a relief valve.
Connection guaranteed: a wide range of functions and variants - always harmonised to the respective requirements.
Exhaust air/supply air flow control or without non-return function
Flow rate 15 ... 4,300 l/min
Threaded connectors M3 ... G3/4
Push-in fittings QS3 ... QS 12 or PK-3 ... PK-6
Variants with increased corrosion resistance
B&G Flo-Control Valves are used for preventing gravity flow in forced water systems and to permit summer-winter operation of indirect water heaters. Flo-Control Valves in NPT sizes Ύ" to 2" are made in combination straight-angle patterns permitting installation in either horizontal or vertical pipe lines. Larger sizes may be furnished in either straight or angle patterns. Removeable top cap allows easy cleaning and service without removing pipe connections. Manual operating position for vertical lift disc to permit gravity circulation.
A family of in-line composite body flow controls, needle valves, and check valves that are tough and corrision resistant. Four stage, tapered needle design provides infinite control. Tamper resistant locking ring prevents unwanted adjustments to the valves. These can be used in-line or be panel mounted. ARO's 360 degree Swivel Right Angle Flow Controls are ready for installation on all ARO Cylinders.
Designed to precisely control the flow of adhesives and sealants during automated dispensing applications, this compact and lightweight valve mounts easily onto either the end of a robot arm or an XY table.
KOFLOC 2203
The KOFLOC Variable Secondary Pressure Flow Controller Valve MODEL 2203 SERIES is a control valve for precise control of minute gas flow and maintaining constant flow under fluctuating secondary pressure (outlet), provided the supply pressure remains constant. This characteristic makes it a must-have preliminary valve in many flow control mechanisms. Constructed using high precision parts, the design of the MODEL 2203 SERIES transforms the rotation of the regulating screw to into linear motion of the needle without subjecting it to gaps and vibrations produced by the screw, to ensure stable and even control of minute flow.
FEATURES
♦ Excellent flow stabilization
♦ Clean construction
♦ Independent from secondary pressure fluctuations
APPLICATIONS
♦ Gas chromatography
♦ Environmental analysis
♦ Atomic absorption spectrometry
♦ Gas mixing
♦ R&D
♦ General industrial use
KOFLOC 2412/2412M
The KOFLOC Precision Needle Valve MODEL 2412 SERIES is designed to control minute flows with precision and ease, controlling minute flow stably and accurately, as low as 0.5 ML/MIN. It has been widely used in numerous applications from general industrial applications to analytical equipment such as AAS (Atomic absorption spectrometer). The needle orifice of the MODEL 2412 SERIES has a temperature compensating structure (US P.A.F.) achieving the characteristic of 0.3%/˚C for gas temperatures between 15 ˚C to 35˚C. MODEL 2412 SERIES includes 15 different needle valves to offer optimum flow control corresponding to various flow levels MODEL 2412M SERIES with Multi-Dial is a precision needle valve with a radial gauge to give simple means to approximate flow volume
FEATURES
♦ Accurate control of minute flow
♦ Wide needle variation
♦ Non-rotating needle
♦ Wide operating temperature range
APPLICATIONS
♦ Atomic absorption spectrometer
♦ Burn control
♦ Research and development
♦ Air sampler
♦ Filter testing
♦ Burn control
(2412M)
♦ Can be used as a substitute for a flowmeter
♦ Detection of flow pass resistance fluctuations
The miniature Preset Flow Control is ideal for many applications involving pneumatic systems, including the control of cylinder speed.
The operation of the flow control is based on the movement of a small disc. The flat surface on one side of the orificed disc seals and permits flow through the orifice. The amount of flow permitted in the reverse direction is determined by the orifice size. In the forward direction full flow is permitted. The flow controls design allows a maximum supply pressure of 75 PSI with a minimum cracking pressure of less than 10 H2O. Orifice sizes are available from .004 to .040.
The PCD Series Digital Dual Valve Pressure Controllers are designed for applications that require a precise pressure control device with easy to integrate features specifically for dead ended applications. The PCD series pressure controller provides an RS-232 and a choice of analog output of the pressure signal as a standard feature. Alicat's P series standard digital pressure gauge electronics are integrated with two proportional control valves (a feed valve and an exhaust valve). The PCD series device was designed for applications that have a closed volume or are dead ended.
